[Predictive value of peripheral blood lymphocyte subsets for children with intravenous immunoglobulin-resistant Kawasaki disease].

Objectives: Based on peripheral blood lymphocyte subsets and common laboratory test indexes, this study aimed to construct a predictive scoring system for intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD).

Methods: Children hospitalized in Tianjin Children's Hospital from January 2021 to March 2023 were included in the study (185 cases of IVIG-sensitive KD and 41 cases of IVIG -resistant KD). Forty-six healthy children matched for age and gender were selected as controls.

Computed tomography and magnetic resonance imaging findings of nasal chondromesenchymal hamartoma in a young child: a case report.

Nasal chondromesenchymal hamartoma (NCMH) is a rare destructive benign neoplasm that predominantly develops in infants and young children. The lesion is usually located in the nasal cavity, often in the adjacent paranasal sinuses and orbital region and especially in the ethmoid sinus. Because the imaging characteristics of NCMH often mimic the features of malignant tumors, it is clinically important to study the radiographic appearance of this disease.

[Observation on gametophyte development of Cibotium barometz].

Objective: To observe the spores germinating process of Cibotium barometz, and understand the growth principle provided for experience for indoor culturing and further research.

Method: The spores of C. barometz were cultured both in inorganic medium and in the soil from original habitat, and the whole process of spores germination and the development of gametophytic were observed under microscope.
